CLARDING-MACHINEL SPECIFICATION forming part of Letters Patent No. 367,853, dated August 9, 1887.

Application filed August 5, 1886. Serial No. 210,147. (No model.)

To all whom it may concern.-

Be it known that I, AUGUSTUS E. SOHMID, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oarding-lifachines, of which thefollowing is a-specification.

My invention relates to machines for carding animal or vegetable fiber, and especially that class of such machines in which a swing ing and astalion'ary carding-frame with a convex and concave actingsiirface, respectively, are used, together with devices for adjusting one such frame in relation to the other; and my invention consists in certain novel features of construction, hereinafter described and claimed, for effecting an easy and rapid oper ation of such machines.

In the accompanying drawings,Figu rel represents a side view of a carding-machine embodying my invention as it appears when one side of the frame is removed. Fig. 2 represents an end view thereof.

Similar letters of reference indicate corresponding parts.

The letter A indicates the main frame, comprising the legs B B, braces O 0, sides D D, and ends E E, the sides and ends forming a case, in which the stationary frame G is arranged to move upward and downward.

S denotes the swinging frame, which is arranged beneath the stationary frame G in fixed bearings on opposite sides of the machineframe.

A treadle, K, f ulcru-med on the crossrod d, is connected to the swinging frame by the rod L, which is pivotally attached to one end of said frame and to the treadle at or about its middle point, while to the opposite end of said frame are attached the spiral springs L L, which have their lower ends attached to said rod a, whereby, as is obvious, a reciprocating movement may be imparted to the swinging frame.

The acting surface of the swinging frame S is convex, while that of the stationary frame G is concave, one being concentric with the other, and. both frames are provided with bent teeth, the teeth 2' of the swinging frame being preferably bent in one and the same direction and the teeth 0 of the stationary frame in opposite direction, the teeth of one frame intermeshing with those of the other. The stationary'frame is provided with upright bars P P,

a spur, c, which passes through the proper 1e ver and engages one of a series of holes (not shown) in the sides D D of the main frame, thereby holding said levers, together with the stationary frame, in the desired position.

In practice the swinging frame S is brought forward by means of the treadle K to the position shown by dotted lines in Fig. 1, and the material to be carded is fed to said frame through an opening, J, in one end of the machine, the operator taking his place on a. seat, H, opposite to said opening. The pressure on the treadle is then removed, when, by the action of the springs L L, the swinging frame S is forced to a' rear position, with the effect of exposing the material to the action of, the teeth of both frames, the carded material discharging at the rear end, S, of the swinging frame.

In lieu of the treadle K. and springs L L, any'other suitable operating mechanism may be connected with the swinging frame S-as, for example, the pitman of a crank, M, upon a shaft, R, for permitting the use of steam or other power.

By the position of the swinging frame S the concave surface thereof acts as a bed for the material to be carded, and, due to the fact that the material has a tendency to discharge from said surface by gravity, a very rapid carding operation may be effected without danger of clogging the teeth of the frames, while by the arrangement of the swinging frame in fixed bearings it is made practicable to employ an operating mechanism, as described, in connection with the swinging frame, inasmuch as the latter preserves a fixed relation to said mechanism, and is not affected by the adjustment of faces being provided with intermeshing bent teeth, adjusting devices for the stationary frame, and operating mechanism for the swinging frame, consisting of the treadle, the rod, and the springs, substantial] y as described.

Signed at New York, in the county of New York and State of New York, this 14th day of July, A. D. 1886.
